HP Recommended

I have a 3301CDW that has been connected via AirPrint for quite some time and working fine. It became inaccessible/offline from all machines and mobile devices in my Unifi network. Of note, another Brother printer in the Airprint network is fine. 

The 3301 can see the HP cloud, and I can ping it from my Unifi router, but no other device on the network can see it via ping or any discovery protocol. 

I don't think it is a Bonjour issue since other printers work in the network, and a compare of the network settings for both in the Unifi console shows no differences. 

I am running out of ideas. I have factory reset and reconnected the printer.
